SIGNAL FOR BALING-PRESSES.

Application filed December 9, 1912.

To all whom it may concern:

Be it known that I, ARTHUR B. CORNELL, a citizen of the United States,residing in Ottawa township, in the county of Franklin and State ofKansas, have invented certain new and useful Improvements in Signals forBaling-Presses, of which the following is a specification.

This invention relates to signals for baling presses, and has for itsobject to produce a signal which shall invariably operate when a balehas attained a predetermined length, viz., a size not too large to beencompassed by a standard bale tie.

With this general object in view, the invention consists in certainnovel and peculiar features of construction and organization ashereinafter described and claimed; and in order that it may be fullyunderstood, reference is to be had to the accompanying drawing, inwhich- Figure 1, is a top plan view of a part of a baling press equippedwith a signal embodying my invention. Fig. 2, is a side View of thesame. Fig. 3, is an enlarged vertical section on the line IIIIII of Fig.2. Fig. 4, is a section on the line IVIV of Fig. 8.

In the said drawings, 1 is the baling case of a baling press of anysuitable type, and pivoted thereto at 2, is a holder 3, to be swung intothe hopper 4, to effect the insertion of a division block 5, in thebaling case, the holder being swung back to. its initial position asshown, after the block has been properly placed, as customary. Securedto the top of the case is a bracket 6, and pivoted to the same at 7, isone end of a toggle, consisting of a link 8, and a link 9, the rear orfree end of the latter being preferably equipped with an antifrictionroller 10, to travel back and forth on the case with the minimumfriction. A spring 11 is secured at one end to bracket 6 and at itsopposite end to the pivot 7 rigid with toggle link 8, for the purpose ofholding the roller 10 upon the baling case with considerable pressure,and journaled on the toggle at the pivotal point of connection of itslinks, is a toothed wheel 12, which normally depends through a slot 13in the baling case and engages a bale, not shown, in such case. Thewheel 12 is provided with a plurality of laterally projecting pins 14,for a purpose which hereinafter appears, and a spring 15 is employed toresist the turning movement imparted to the wheel by the bale and toreturn Specification of Letters Patent.

the wheel to its initial position when withdrawn from engagement withthe bale, as hereinafter explained, and to guard against excessiverotation of the wheel either forward or backward, it is provided with astop 16, for alternately engaging the under and upper sides of a stop17, projecting from the link 8 of the toggle.

18 is a gong carried by link 8 and 19 a spring clapper mounted on a bolt20 secured to said link and provided with an arm 21 underlying a boss 22whereby a spring 23 is prevented from holding the clapper in constantengagement with the gong, said spring 23 being secured at its upper endto a loop 24, in the clapper, and at its lower end to an eye 25,projecting from link 8.

26, is, a trigger pivoted on bolt 20, and provided with an inwardlyprojecting arm 27, resting on the adjacent arm 21, of the clapper asshown in Fig. 4, and in the path of the pins 14 of the wheel, and toquickly return this trigger to normal position after it is raised orlowered by the pins 14, in passing, a spring 28 is secured at one end tothe trigger and at the other end to a suitable point, preferably to theclapper.

29 is a rod connecting the holder and arm 9 of the toggle so thatmovement of the holder into the hopper shall contract the toggle andraise the wheel 12 from the bale and opposite movement of the holdershall reexpand the toggle and assist spring 11 in restoring the saidWheel to operative position.

To accommodate the forming of bales of different lengths, it will ofcourse be necessary to equip. the device with a proportionately largeror smaller wheel, and in this event it is desirable that the link 8shall be extensible. The said link therefore consists of two members orplates adjust-ably secured together by bolts 30.

As the formation of a bale is started, the stop 16 is in engagement withthe underside of the fixed stop 17, and it will be seen that the bale inits formation and movement, will impart rotation to the wheel in thedirection indicated by the arrow thereon, see Fig. 2, and that sometimebefore the wheel has completed a revolution, the first pin 14 willdepress and release the trigger 26, and thereby raise the hammer end ofthe clapper, against the resistance of spring 23, so that the latterwill cause said end to strike the gong as the trigger is released bysaid pin and thus signal the attendant. Shortly afterward this signal isrepeated through the instrumentality of the second pin and upon theoperation of the signal by the third or last pin, the attendant is madeaware that the bale has attained the proper length and that it is timeto insert the division block, it being noted that at such time the stop16 is engaging the upper side of the fixed stop 17 In swinging theholder into the hopper to insert the block, the rod 29 is pulled forwardand exerts corresponding force on the link 9, of the toggle, and causesthe roller 10 thereof to roll upon the top of the case and thus raisethe joint of the toggle links until the wheel 12 is totally withdrawnfrom the bale. As this object is accomplished, the spring 15, which wasplaced under tension by the rotatable movement imparted to the wheel bythe bale, is left free to rotate wheel 12 back to its original position,that is until the stop 16 strikes the underside of the stop 17 and thusarrests the back rotation of the.

wheel. It will thus be seen that the Wheel will invariably rotate apredetermined distance before it sounds the final signal and thatconsequently the bales will always be, of what may be called, apredetermined size, that is a size which can be readily encompassed bystandard bale ties, not shown.

The desirability of a signal for calling attention to the fact that itis time to insert a division block in the baling case is recognized, butheretofore, so far as my knowledge extends, the wheel driven by theadvancing bale frequently overruns if not closely watched, and as aresult it is necessary to frequently rebale large volumes of materialbecause, if the wheel overruns materially on any particular bale, thelatter cannot be encompassed by the bale tie wires. Furthermore wherethe wheel overruns the length of the bales cannot be accurately gagedwithout close watching on the part of the attendant. Vith my signalmechanism, the wheel stops when the bale has attained its maximumlength, which condition the attendant will soon perceive and remedy byoperating the division block holder. I Vhile this signal mechanism doesnot prevent a very careless attendant from wasting time and labor, itdoes insure that each bale shall start when the movable stop on wheel 12is in engagement with the underside of the fixed stop 17 of the toggle,and also invariably signals the attendant when the bale has attained apredetermined length, which of course is not true of any signalmechanism actuated by a wheel capable of overrunning.

From the above description it will be apparent that I have produced asignal for baling presses embodying the features of advantage enumeratedas desirable and I wish it to be understood that while Ihave'illustrated and described the preferred embodiment of the same, Ireserve the right to make all changes properly falling within the spiritand scope of the appended laims.

I claim 1.
